Condensers,Evaporators Ec Cooling Fan With Sheet Steel For Zw250c-230d3-00
1． As the rotor is mounted to interior, the external rotor fan is more compact constructed, smaller and easy to abstract heat., thus ensure to maximum the reliability of fan operation,
2． Sustainable speed control benefits to achieve low operating costs, reduce CO2 emissions protect the environment, enable the direct, simple communication between the host controller and the system,
3． Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation
4． Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via 180,sine SVPWM(Space Vector PWM)to meet customer needs
5． Intelligent EC fan can support users to realize centralized operation control by 485 bus and monitor as many as 255 fans
6． EC fan has comprehensive protection function, such as phase failure, overvoltage, undervoltage, locked-rotor, over current and temperature protection
Air-Conditioning Terminals Ec Axial Fan With Sheet Steel For Zw200c-230d3-00
1. Connect the impeller and outer rotor directly, make full use of the space
2. The double-single balance of the whole unit makes the fan operate more smoothly and durable
3. Operating life is more durable through selecting the high-eng deep groove ball bearing

Durable Cooling Fan With Zw450c-230d3-00 For Eshaust Ventilation
1． EC fans includes AC input driven brushless DC fan with integrated design of AC-DC transformation circuit, the PFC circuit, the BLDC drive circuit, interface circuit. Due to the internal integration of the AC-DC converter circuit, the consumption of power will be reduced to facilitate the design and application of the overall power system in customer.
2． Brushless DC external rotor motor belongs to non-mechanical brush(commutator)DC motor which enforces the winding current commutation through electronic commutator (position sensing, non- position sensing),achieve the speed control function with PAM or PWM control
3． Enable the selection of different power levels thus to get the best match of price and performance according to customers’load requirements
4． As the rotor is mounted to interior, the external rotor fan is more compact constructed, smaller and easy to abstract heat., thus ensure to maximum the reliability of fan operation,
5． Sustainable speed control benefits to achieve low operating costs, reduce CO2 emissions protect the environment, enable the direct, simple communication between the host controller and the system,
6． Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation
